RESUMO
Potentially mutagenic impurities are likely to be formed in any drug substance, since their synthesis requires reactive intermediates which may also react with DNA. The ICH M7 guideline, which defines how to risk assess and control mutagenic impurities, was first published in 2014 and is not to be applied retrospectively; however, some impurities have been found above the permitted limits in drug products which were already on the market. This study assessed the implications of applying ICH M7 retrospectively to anti-hypertensive drugs marketed in Brazil by performing a risk assessment and establishing control strategies. The manufacturing processes of 15 drug substances were evaluated and 262 impurities were identified, from which 21% were classified as potentially mutagenic. Most of the impurities were identified below ICH M7 acceptable limits, except for impurities described in a pharmacopoeial monograph. Compendial specifications are defined based on scientific evidence and play an important role in setting quality and safety standards for pharmaceuticals, however there are opportunities for further alignment with ICH guidelines, aiming for a holistic assessment of the impurities profile to ensure the safety of medicines.

BACKGROUND: Health plan coverage is central to patient access to care, especially for rare, chronic diseases. For specialty drugs, coverage varies, resulting in barriers to access. Pulmonary arterial hypertension (PAH) is a rare, progressive, and fatal disease. Guidelines suggest starting or rapidly escalating to combination therapy with drugs of differing classes (phosphodiesterase 5 inhibitors [PDE5is], soluble guanylate cyclase stimulators [sGC stimulators], endothelin receptor antagonists [ERAs], and prostacyclin pathway agents [PPAs]). OBJECTIVE: To assess the variation in commercial health plan coverage for PAH treatments and how coverage has evolved. To examine the frequency of coverage updates and evidence cited in plan policies. METHODS: We used the Tufts Medical Center Specialty Drug Evidence and Coverage database, which includes publicly available specialty drug coverage policies. Overall, and at the drug and treatment class level, we identified plan-imposed coverage restrictions beyond the drug's US Food and Drug Administration label, including step therapy protocols, clinical restrictions (eg, disease severity), and prescriber specialty requirements. We analyzed variation in coverage restrictiveness and how coverage has changed over time. We determined how often plans update their policies. Finally, we categorized the cited evidence into 6 different types. RESULTS: Results reflected plan coverage policies for 13 PAH drugs active between August 2017 and August 2022 and issued by 17 large US commercial health plans, representing 70% of covered lives. Coverage restrictions varied mainly by step therapy protocols and prescriber restrictions. Seven plans had step therapy protocols for most drugs, 9 for at least one drug, and 1 had none. Ten plans required specialist (cardiologist or pulmonologist) prescribing for at least one drug, and 7 did not. Coverage restrictions increased over time: the proportion of policies with at least 1 restriction increased from 38% to 73%, and the proportion with step therapy protocols increased from 29% to 46%, with generics as the most common step. The proportion of policies with step therapy protocols increased for every therapy class with generic availability: 18% to 59% for ERAs, 33% to 77% for PDE5is, and 33% to 43% for PPAs. The proportion of policies with prescriber requirements increased from 24% to 48%. Plans updated their policies 58% of the time annually and most often cited the 2019 CHEST clinical guidelines, followed by randomized controlled trials. CONCLUSIONS: Plan use of coverage restrictions for PAH therapies increased over time and varied across both drugs and plans. Inconsistency among health plans may complicate patient access and reduce the proportion who can persist on PAH treatments.

BACKGROUND: Deprescribing of medication for cardiovascular risk factors and diabetes has been incorporated in clinical guidelines but proves to be difficult to implement in primary care. Training of healthcare providers is needed to enhance deprescribing in eligible patients. This study will examine the effects of a blended training program aimed at initiating and conducting constructive deprescribing consultations with patients. METHODS: A cluster-randomized trial will be conducted in which local pharmacy-general practice teams in the Netherlands will be randomized to conducting clinical medication reviews with patients as usual (control) or after receiving the CO-DEPRESCRIBE training program (intervention). People of 75 years and older using specific cardiometabolic medication (diabetes drugs, antihypertensives, statins) and eligible for a medication review will be included. The CO-DEPRESCRIBE intervention is based on previous work and applies models for patient-centered communication and shared decision making. It consists of 5 training modules with supportive tools. The primary outcome is the percentage of patients with at least 1 cardiometabolic medication deintensified. Secondary outcomes include patient involvement in decision making, healthcare provider communication skills, health/medication-related outcomes, attitudes towards deprescribing, medication regimen complexity and health-related quality of life. Additional safety and cost parameters will be collected. It is estimated that 167 patients per study arm are needed in the final intention-to-treat analysis using a mixed effects model. Taking loss to follow-up into account, 40 teams are asked to recruit 10 patients each. A baseline and 6-months follow-up assessment, a process evaluation, and a cost-effectiveness analysis will be conducted. DISCUSSION: The hypothesis is that the training program will lead to more proactive and patient-centered deprescribing of cardiometabolic medication. By a comprehensive evaluation, an increase in knowledge needed for sustainable implementation of deprescribing in primary care is expected. TRIAL REGISTRATION: The study is registered at ClinicalTrials.gov (identifier: NCT05507177).

OBJECTIVE: To evaluate the health benefits and intervention efficiency of different strategies of initiating antihypertensive therapy for the primary prevention of cardiovascular diseases in a community-based Chinese population from the Chinese electronic health records research in Yinzhou (CHERRY) study. METHODS: A decision-analytic Markov model was used to simulate and compare different antihypertensive initiation strategies, including: Strategy 1, initiation of antihypertensive therapy for Chinese adults with systolic blood pressure (SBP) ≥140 mmHg (2020 Chinese guideline on the primary prevention of cardiovascular diseases); Strategy 2, initiation of antihypertensive therapy for Chinese adults with SBP ≥130 mmHg; Strategy 3, initiation of antihypertensive therapy for Chinese adults with SBP≥140 mmHg, or with SBP between 130 and 140 mmHg and at high risk of cardiovascular diseases (2017 American College of Cardiology/American Heart Association guideline for the prevention, detection, evaluation, and management of high blood pressure in adults); Strategy 4, initiation of antihypertensive therapy for Chinese adults with SBP≥160 mmHg, or with SBP between 140 and 160 mmHg and at high risk of cardiovascular diseases (2019 United Kingdom National Institute for Health and Care Excellence guideline for the hypertension in adults: Diagnosis and management). The high 10-year cardiovascular risk was defined as the predicted risk over 10% based on the 2019 World Health Organization cardiovascular disease risk charts. Different strategies were simulated by the Markov model for ten years (cycles), with parameters mainly from the CHERRY study or published literature. After ten cycles of simulation, the numbers of quality-adjusted life years (QALY), cardiovascular events and all-cause deaths were calculated to evaluate the health benefits of each strategy, and the numbers needed to treat (NNT) for each cardiovascular event or all-cause death could be prevented were calculated to assess the intervention efficiency. One-way sensitivity analysis on the uncertainty of incidence rates of cardiovascular disease and probabilistic sensitivity analysis on the uncertainty of hazard ratios of interventions were conducted. RESULTS: A total of 213 987 Chinese adults aged 35-79 years without cardiovascular diseases were included. Compared with strategy 1, the number of cardiovascular events that could be prevented in strategy 2 increased by 666 (95% UI: 334-975), while the NNT per cardiovascular event prevented increased by 10 (95% UI: 7-20). In contrast to strategy 1, the number of cardiovascular events that could be prevented in strategy 3 increased by 388 (95% UI: 194-569), and the NNT per cardiovascular event prevented decreased by 6 (95% UI: 4-12), suggesting that strategy 3 had better health benefits and intervention efficiency. Compared to strategy 1, although the number of cardiovascular events that could be prevented decreased by 193 (95% UI: 98-281) in strategy 4, the NNT per cardiovascular event prevented decreased by 18 (95% UI: 13-37) with better efficiency. The results were consistent in the sensitivity analyses. CONCLUSION: When initiating antihypertensive therapy in an economically developed area of China, the strategy combined with cardiovascular risk assessment is more efficient than those purely based on the SBP threshold. The cardiovascular risk assessment strategy with different SBP thresholds is suggested to balance health benefits and intervention efficiency in diverse populations.

OBJECTIVE: To examine the association between missed CMS Star Ratings quality measures for medication adherence over 3 years for diabetes, hypertension, and hyperlipidemia medications (9 measures) and health care utilization and relative costs. STUDY DESIGN: Retrospective cohort study. METHODS: The study examined eligible patients who qualified for the diabetes, statin, and renin-angiotensin system antagonist medication adherence measures in 2018, 2019, and 2020 and were continuously enrolled in a Medicare Advantage prescription drug plan from 2017 through 2021. A total of 103,900 patients were divided into 4 groups based on the number of adherence measures missed (3 medication classes over 3 years): (1) missed 0 measures, (2) missed 1 measure, (3) missed 2 or 3 measures, and (4) missed 4 or more measures. To achieve a quality measure, patients had to meet the Pharmacy Quality Alliance 80% threshold of proportion of days covered during the calendar year. RESULTS: The mean age of the cohort was 71.1 years, and 49.9% were female. Compared with patients who missed 0 of 9 adherence measures, those who missed 1 measure, 2 or 3 measures, and 4 or more measures experienced 12% to 26%, 22% to 42%, and 24% to 50% increased risks, respectively, of all-cause and diabetes-related inpatient stays and all-cause and diabetes-related emergency department visits (all P values < .01). Additionally, patients who missed 1, 2 or 3, and 4 or more adherence measures experienced 14%, 19%, and 20% higher monthly medical costs, respectively. CONCLUSIONS: Missing Star Ratings quality measures for medication adherence was associated with an increased likelihood of health care resource utilization and increased costs for patients taking medications to treat diabetes, hypertension, and hyperlipidemia.

BACKGROUND: We examined the association of multilevel social determinants of health with incident apparent treatment-resistant hypertension (aTRH). METHODS AND RESULTS: We analyzed data from 2774 White and 2257 Black US adults from the REGARDS (Reasons for Geographic and Racial Differences in Stroke) study taking antihypertensive medication without aTRH at baseline to estimate the association of social determinants of health with incident aTRH. Selection of social determinants of health was guided by the Healthy People 2030 domains of education, economic stability, social context, neighborhood environment, and health care access. Blood pressure (BP) was measured during study visits, and antihypertensive medication classes were identified through a pill bottle review. Incident aTRH was defined as (1) systolic BP ≥140 mm Hg or diastolic BP ≥90 mm Hg, or systolic BP ≥130 mm Hg or diastolic BP ≥80 mm Hg for those with diabetes or chronic kidney disease while taking ≥3 classes of antihypertensive medication or (2) taking ≥4 classes of antihypertensive medication regardless of BP level, at the follow-up visit. Over a median 9.5 years of follow-up, 15.9% of White and 24.0% of Black adults developed aTRH. A percent of the excess aTRH risk among Black versus White adults was mediated by low education (14.2%), low income (16.0%), not seeing a friend or relative in the past month (8.1%), not having someone to care for them if ill or disabled (7.6%), lack of health insurance (10.6%), living in a disadvantaged neighborhood (18.0%), and living in states with poor public health infrastructure (6.0%). CONCLUSIONS: Part of the association between race and incident aTRH risk was mediated by social determinants of health.

BACKGROUND: Medicare supplement insurance, or Medigap, covers 21% of Medicare beneficiaries. Despite offsetting some out-of-pocket (OOP) expenses, remaining OOP costs may pose a barrier to medication adherence. This study aims to evaluate how OOP costs and insurance plan types influence medication adherence among beneficiaries covered by Medicare supplement plans. METHODS: We conducted a retrospective analysis of the Merative MarketScan Medicare Supplement Database (2017-2019) in Medigap enrollees (≥65 years) with hypertension. The proportion of days covered (PDC) was a continuous measure of medication adherence and was also dichotomized (PDC ≥0.8) to quantify adequate adherence. Beta-binomial and logistic regression models were used to estimate associations between these outcomes and insurance plan type and log-transformed OOP costs, adjusting for patient characteristics. RESULTS: Among 27,407 patients with hypertension, the average PDC was 0.68â ±â 0.31; 47.5% achieved adequate adherence. A mean $1 higher in 30-day OOP costs were associated with a 0.06 (95% confidence intervals [CIs]: -0.09 to -0.03) lower probability of adequate adherence, or a 5% (95% CI: 4%-7%) decrease in PDC. Compared with comprehensive plan enrollees, the odds of adequate adherence were lower among those with point-of-service plans (odds ratio [OR]: 0.69, 95% CI: 0.62-0.77), but higher among those with preferred provider organization (PPO) plans (OR: 1.08, 95% CI: 1.01-1.15). Moreover, the association between OOP costs and PDC was significantly greater for PPO enrollees. CONCLUSIONS: While Medicare supplement insurance alleviates some OOP costs, different insurance plans and remaining OOP costs influence medication adherence. Reducing patient cost-sharing may improve medication adherence.

INTRODUCTION: Several observational studies have been conducted to assess the prevalence of cardiovascular risk factors in hypertensive patients; however, none has yet investigated prevalence, clustering, and current management of cardiovascular risk factors upon first referral to hypertension specialists, which is the aim of the present study. METHODS: Consecutive adult outpatients with essential/secondary hypertension were included at the time of their first referral to hypertension specialists at 13 Italian centers in the period April 2022-2023 if they had at least one additional major cardiovascular risk factor among LDL-hypercholesterolemia, type 2 diabetes, and cigarette smoking. Prevalence, degree of control, and current management strategies of cardiovascular risk factors were assessed. RESULTS: A total of 255 individuals were included, 40.2% women and 98.4% Caucasian. Mean age was 60.3±13.3 years and mean blood pressure [BP] was 140.3±17.9/84.8±12.3 mmHg). Most participants were smokers (55.3%), had a sedentary lifestyle (75.7%), suffered from overweight/obesity (51%) or high LDL-cholesterol (41.6%), had never adopted strategies to lose weight (55.7%), and were not on a low-salt diet (57.4%). Only a minority of patients reported receiving specialist counseling, and 27.9% had never received recommendations to correct unhealthy lifestyle habits. Nearly 90% of individuals with an estimated high/very high cardiovascular risk profile did not achieve recommended LDL-cholesterol targets. CONCLUSIONS: In patients with hypertension, both pharmacological and lifestyle therapeutic advice are yet to improve before referral to hypertension specialists. This should be considered in the primary care setting in order to optimize cardiovascular risk management strategies.

OBJECTIVE: The purpose of this study is to explore the change in physicians' hypertension treatment behavior before and after the reform of the capitation in county medical community. METHODS: Spanning from January 2014 to December 2019, monthly data of outpatient and inpatient were gathered before and after the implementation of the reform in April 2015. We employed interrupted time series analysis method to scrutinize the instantaneous level and slope changes in the indicators associated with physicians' behavior. RESULTS: Several indicators related to physicians' behavior demonstrated enhancement. After the reform, medical cost per visit for inpatient exhibited a reverse trajectory (-53.545, 95%CI: -78.620 to -28.470, p < 0.01). The rate of change in outpatient drug combination decelerated (0.320, 95%CI: 0.149 to 0.491, p < 0.01). The ratio of infusion declined for both outpatient and inpatient cases (-0.107, 95%CI: -0.209 to -0.004, p < 0.1; -0.843, 95%CI: -1.154 to -0.532, p < 0.01). However, the results revealed that overall medical cost per visit and drug proportion for outpatient care continued their initial upward trend. After the reform, the decline of drug proportion for outpatient care was less pronounced compared to the period prior to the reform, and length of stay also had a similar trend. CONCLUSION: To some extent, capitation under the county medical community encourages physicians to control the cost and adopt a more standardized diagnosis and treatment behavior. This study provides evidence to consider the impact of policy changes on physicians' behavior when designing payment methods and healthcare systems aimed at promoting PHC.

BACKGROUND: Medication nonadherence is a barrier to hypertension control. The Centers for Disease Control and Prevention recommends prescribing 90-day fills for maintenance medications yet antihypertensives are often dispensed as 30-day fills. Our objectives were to examine how often patients receive 30-day supplies of medication despite prescriptions for longer duration and to examine the effect of medication fill duration on adherence and hypertension control. METHODS: We conducted a retrospective cohort study of pediatric patients with hypertension over a 3-year period. For each patient, days prescribed per fill were compared to days dispensed per fill using pharmacy reports and insurance claim data. Proportion of Days Covered (PDC) was calculated to estimate adherence. Hypertension control was determined by provider assessment of control and blood pressure measurement at the final visit. RESULTS: Final cohort included 449 patients. A total of 70% had at least one prescription for ≥ 90 days but only 37% had at least one dispense for ≥ 90 days. There was no difference in the likelihood of being prescribed a 90-day fill by insurance type (public vs. private); however, patients with public insurance were less likely to be dispensed a 90-day fill (OR = 0.068, p < 0.001). Patients who received 90-day fills had better adherence (median PDC 77.5% vs. 58.1%, p < 0.001) and were more likely to have hypertension control based on provider assessment. CONCLUSIONS: Longer fill duration is associated with improved adherence and hypertension control. Patients with public insurance are markedly less likely to be dispensed 90-day fills, a modifiable barrier to improving adherence.

BACKGROUND: In 2009, a workplace-based hypertension management program was launched among men with hypertension in the Kailuan study. This program involved monitoring blood pressure semimonthly, providing free antihypertensive medications, and offering personalized health consultations. However, the cost-effectiveness of this program remains unclear. METHODS AND RESULTS: This analysis included 12 240 participants, with 6120 in each of the management and control groups. Using a microsimulation model derived from 10-year follow-up data, we estimated costs, quality-adjusted life years (QALYs), life-years, and incremental cost-effectiveness ratios (ICERs) for workplace-based management compared with routine care in both the study period and over a lifetime. Analyses are conducted from the societal perspective. Over the 10-year follow-up, patients in the management group experienced an average gain of 0.06 QALYs with associated incremental costs of $633.17 (4366.85 RMB). Projecting over a lifetime, the management group was estimated to increase by 0.88 QALYs or 0.92 life-years compared with the control group, with an incremental cost of $1638.64 (11 301.37 RMB). This results in an incremental cost-effectiveness ratio of $1855.47 per QALY gained and $1780.27 per life-year gained, respectively, when comparing workplace-based management with routine care. In probabilistic sensitivity analyses, with a threshold willingness-to-pay of $30 765 per QALY (3 times 2019 gross domestic product per capita), the management group showed a 100% likelihood of being cost-effective in 10 000 samples. CONCLUSIONS: Workplace-based management, compared with routine care for Chinese men with hypertension, could be cost-effective both during the study period and over a lifetime, and might be considered in working populations in China and elsewhere.

OBJECTIVES: India has taken several initiatives to provide health care to its population while keeping the related expenditure minimum. Since cardiovascular diseases are the most prevalent chronic conditions, in the present study, we aimed to analyze the difference in prices of medicines prescribed for three cardiovascular risk factors, based on (a) listed and not listed in the National List of Essential Medicines (NLEM) and (b) generic and branded drugs. MATERIALS AND METHODS: Outpatient prescriptions for diabetes mellitus, hypertension, and dyslipidemia were retrospectively analyzed from 12 tertiary centers. The prices of medicines prescribed were compared based on presence or absence in NLEM India-2015 and prescribing by generic versus brand name. The price was standardized and presented as average price per medicine per year for a given medicine. The results are presented in Indian rupee (INR) and as median (range). RESULTS: Of the 4,736 prescriptions collected, 843 contained oral antidiabetic, antihypertensive, and/or hypolipidemic medicines. The price per medicine per year for NLEM oral antidiabetics was INR 2849 (2593-3104) and for non-NLEM was INR 5343 (2964-14364). It was INR 806 (243-2132) for generic and INR 3809 (1968-14364) for branded antidiabetics. Antihypertensives and hypolipidemics followed the trend. The price of branded non-NLEM medicines was 5-22 times higher compared to generic NLEM which, for a population of 1.37 billion, would translate to a potential saving of 346.8 billion INR for statins. The variability was significant for sulfonylureas, angiotensin receptor blockers, beta-blockers, diuretics, and statins (P < 0.0001). CONCLUSION: The study highlights an urgent need for intervention to actualize the maximum benefit of government policies and minimize the out-of-pocket expenditure on medicines.

BACKGROUND: The digital transformation of medical data enables health systems to leverage real-world data from electronic health records to gain actionable insights for improving hypertension care. METHODS AND RESULTS: We performed a serial cross-sectional analysis of outpatients of a large regional health system from 2010 to 2021. Hypertension was defined by systolic blood pressure ≥140 mm Hg, diastolic blood pressure ≥90 mm Hg, or recorded treatment with antihypertension medications. We evaluated 4 methods of using blood pressure measurements in the electronic health record to define hypertension. The primary outcomes were age-adjusted prevalence rates and age-adjusted control rates. Hypertension prevalence varied depending on the definition used, ranging from 36.5% to 50.9% initially and increasing over time by ≈5%, regardless of the definition used. Control rates ranged from 61.2% to 71.3% initially, increased during 2018 to 2019, and decreased during 2020 to 2021. The proportion of patients with a hypertension diagnosis ranged from 45.5% to 60.2% initially and improved during the study period. Non-Hispanic Black patients represented 25% of our regional population and consistently had higher prevalence rates, higher mean systolic and diastolic blood pressure, and lower control rates compared with other racial and ethnic groups. CONCLUSIONS: In a large regional health system, we leveraged the electronic health record to provide real-world insights. The findings largely reflected national trends but showed distinctive regional demographics and findings, with prevalence increasing, one-quarter of the patients not controlled, and marked disparities. This approach could be emulated by regional health systems seeking to improve hypertension care.

The aim of this study is to evaluate the developments in the treatment and prevalence of hypertension by demographic subgroups in least developed area of China in 2012 and 2022. This population-based cross-sectional study was conducted in 2012 and 2022, we applied stratified multistage random sampling to investigate residents aged 18 years or older in Gansu, the least developed province in the northwest of China. Questionnaires and anthropometric measurements were given to all respondents. The standardized prevalence of hypertension in adults in Gansu increased from 26.1% in 2012 to 28.8% in 2022. Compared with 2012, the control rate remains decreased despite the significantly improved awareness and treatment rates of hypertension in 2022. Apart from the reversal of the control rate, the trend of higher prevalence in men and higher awareness and treatment rates in women has not changed. There was an obviously increase in the proportion of participants who had received health education and hypertension management services from medical workers. The treatment was still primarily monotherapy, and there was no significant improvement in the prescription of medication. The prevalence of hypertension has increased mildly in the least developed region of China over the past decade, and the challenge of hypertension management has shifted from increasing awareness and treatment rates to increasing control rates. The onset and control of hypertension are affected by education methods, BMI, local economic conditions and other factors, and targeted strategies can be adopted to strengthen the management of hypertension in economically underdeveloped areas of China.

The purpose of this study was to evaluate the economics of Annao Pills combined with antihypertensive drugs in the treatment of primary hypertension in the Chinese medical setting. TreeAge pro 2018 was used for cost-effect analysis and sensitivity analysis of the two treatment regimens. The intervention time of the simulation model was 2 weeks. The cost parameters were derived from Yaozhi.com, and the effect parameters were based on Meta-analysis of randomized controlled trial(RCT) involving Annao Pills. The experimental group was treated with Annao Pills combined with anti-hypertensive drugs(nifedipine controlled-release tablets + losartan potassium tablets), and the control group was treated with anti-hypertensive drugs(nifedipine controlled-release tablets + losartan potassium tablets). The basic analysis showed that the incremental cost-effect ratio(ICER) of the two groups was 2 678.67 yuan, which was less than 7.26% of the per capita disposable income in 2022. That is, compared with anti-hypertensive drugs alone, Annao Pills combined with antihypertensive drugs cost 2 678.67 yuan more for each additional patient with primary hypertension. The results of sensitivity analysis verified the robustness of the basic analysis results. The probability sensitivity results showed that when the patient's personal willingness to pay the price was higher than 2 650 yuan, the probability of the regimen in the experimental group was higher, which was consistent with the results of the basic analysis. In conclusion, when the price was higher than 2 650 yuan, Annao Pills combined with anti-hypertensive drugs was more economical than anti-hypertensive drugs alone in terms of improving the response rate of the patients with primary hypertension.

INTRODUCTION: Hypertension and diabetes are modifiable risk factors for dementia. We aimed to assess rural-urban disparities in the diagnosis and treatment of these conditions among aging Indians. METHODS: Participants (n = 6316) were from two parallel, prospective aging cohorts in rural and urban India. Using self-report and clinical/biochemical assessments, we subdivided participants with diabetes and hypertension into undiagnosed and untreated groups. Logistic regression and Fairlie decomposition analysis were the statistical methods utilized. RESULTS: There was a significant rural-urban disparity in undiagnosed hypertension (25.14%), untreated hypertension (11.75%), undiagnosed diabetes (16.94%), and untreated diabetes (11.62%). Further, sociodemographic and lifestyle factors, such as age and tobacco use were the common contributors to the disparities in both undiagnosed hypertension and undiagnosed diabetes, whereas education and body mass index (BMI) were significant contributors to the disparity in untreated hypertension. DISCUSSION: Rural Indians face significant healthcare disadvantages as compared to their urban counterparts, which prompts the urgent need for strategies for equitable healthcare.

BACKGROUND: Chronic kidney disease (CKD) is a common comorbidity in patients with apparent treatment-resistant hypertension (aTRH). We assessed clinical outcomes, healthcare resource utilization events, and costs in patients with aTRH or difficult-to-control hypertension and stage 3-4 CKD with uncontrolled vs. controlled BP. METHODS: This retrospective cohort study used linked IQVIA Ambulatory EMR-US and IQVIA PharMetrics Plus claims databases. Adult patients had claims for ≥3 antihypertensive medication classes within 30 days between 01/01/2015 and 06/30/2021, 2 office BP measures recorded 1-90 days apart, ≥1 claim with ICD-9/10-CM diagnosis codes for CKD 3/4, and ≥1 year of continuous enrollment. Baseline BP was defined as uncontrolled (≥130/80 mm Hg) or controlled (<130/80 mm Hg) BP. Outcomes included risk of major adverse cardiovascular events plus (MACE+; stroke, myocardial infarction, heart failure hospitalization), end-stage renal disease (ESRD), healthcare resource utilization events, and costs during follow-up. RESULTS: Of 3,966 patients with stage 3-4 CKD using ≥3 antihypertensive medications, 2,479 had uncontrolled BP and 1,487 had controlled BP. After adjusting for baseline differences, patients with uncontrolled vs. controlled BP had a higher risk of MACE+ (HR [95% CI]: 1.18 [1.03-1.36]), ESRD (1.85 [1.44-2.39]), inpatient hospitalization (rate ratio [95% CI]: 1.35 [1.28-1.43]), and outpatient visits (1.12 [1.11-1.12]) and incurred higher total medical and pharmacy costs (mean difference [95% CI]: $10,055 [$6,741-$13,646] per patient per year). CONCLUSIONS: Patients with aTRH and stage 3-4 CKD and uncontrolled BP despite treatment with ≥3 antihypertensive classes had an increased risk of MACE+ and ESRD and incurred greater healthcare resource utilization and medical expenditures compared with patients taking ≥3 antihypertensive classes with controlled BP.
